Specification of Letters Patent.

Application filed March 29, 1913.

Patent-cd laii.13, 1914. serial No. 757,689.

To all whom it may concern Be it known that 1, CHARLES A. Bnn'r'n Nien, a. citizen of the United States, residing at 228 Ridgewood avenue, in the county oit Kings, city and State of New York, have invented certain new and useful Improvements in Slides, of which the following is a specification.

This invention relates to slides to be used with exhibiting machines, motion picture apparatus, &c., and has for its chief object to provide a slide having cut out lettering or characters which will not catch into the slide carrier when put in the machine.

Other objects are to greatly reinforce the slide and to simplify and cheapen the cost of manufacture, &c., all of which objects are accomplished by the combination and construction of parts herein/after more particularly described and claimed.

In the accompanying drawings: `Figure 1 represents a front elevation of a slide einbodying my invention; F Q. a rear elevation of the same; Fig. 3, a longitudinal section on the line 3 3 of Fig. 1; Fig. 4, a cross-section on the line 1 -4 of Fig. 1; and Fig. 5, a View in front elevation o f the three parts of the slide arranged adjacent each other.

Referring now in detail to the drawings, 1 designates a reinforcing frame of sheet iron or other suitable material and is pro vided with an elliptically shaped opening 2 for the passage of light and to permit part of the facing 3 to be depressed therein.

The front or facing 3 of thin sheet metal is provided with a portion 4 out of which are cut letters or other characters or figures,

v this portion, when the slide is assembled,

registering with the opening 2 in thc frame 1.

5 designates a sheet of mica or other suitable material which ma y be tinted as desired and which is arranged between the facing 3 and the frame 1, extending completely over the opening 2 and behind the portion 4.

ln practice the sheet of mica 5, or other suitable material and the facing 3 are superimposed on the iframe 1, with the edges of the facing 3 overlapping the edges of the frame 1 and with the corners of the facing 3 cut out as :it (i. Next the overlapping edges of facing 3 are bent over the edges of frame 1 and tightly pressed against the rear thereof, and portion it of the facing 3 being in the same operation depressed through the opening 2 in the frame 1. The exact degree of the depression of the portion 4t may be regulated as desired, but I prefer to depress it until its near face is on a plane with the rear face of said frame 1, thus fully protecting the letters, &c., and preventing it from catching in the carrier. Such depression may of course be made also in a separate operation. The out out portions 6 of the part 3 will allow the edges 7 of the facing 3 to be folded smoothly on the rear vof frame 1, without wrinlrling, crushing, Src., at the corners.

lt is to be noted that by depressing the portion 4 through opening 2 the lettering, &c., will be ont of the way of possible harm and accident in the carrier. Also theedge of this depression is gradual, not abrupt, hence nothing will catch on the edge of the depression, thus the objection of a separate folded/marginal strip is avoided.

It is quite obvious that slight changes and alterations may be made in the construction and arrangement of my device, of which only the preferred form is illustrated and described in this application and it is my intention and desire to include all such alterations and changes in the following claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A slide comprising a reinforcing frame provided with an opening, in combination with a sheet metal facing provided with perforations which are in alinement with said opening and having its edges overlap` ping the edges of said frame and pressed against the rear thereof.

2. A slide comprising a reinforcing frame having an opening and a coloring medium titl titi

titl

superimposed thereon, in combination with a sheet metal facing firmly held in superimposed relation on said coloring medium and frame and having :t perforated portion registering with said opening, the said perforated portion being depressed through said opening.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.

CHARLES A. BUETTNER.
